In eonnecuen with this. substitutie@ of another portion-ofthe fabric fofr'that Justlinished very great attention must be paid to makingthe joints between thesucc'essive portions of vthe embroidery practically faultless,.so vthat it'will be practlcally l1mpossi'ble lto detect in the entirelylnished` embroidery where the singly made portions of theembroidery join 'one another.- *1 Hitherto the opinion was prevailing that thefabricmust be stretched out during that exchange of the consecutive portions of thek fabric, or ofthe embroidery respectively,

the roller 5 isthat y receiving the emloroi'djered',y

the rollers is stretched outbetw'ee'nfthe-ho'ri-` zontal rails 6 and'7,'of-'whi'ch at least the nuts, as Shown in Figurer, the mais -0bjeet=-- of*l that adjustment beingy to' stretch" the e fabric' between the rai-ls asremiire'd' v.forthe 'f i embroidery operation@ 1j' f ;V To fix-the joint lineffor thefabri'cyvhileyllo 1itfisloose during the exchange" ofthe' coh'i vsecu'tive portons,the movable frame is-provided with avertical bar 9 which is supported by a pivot -10 situated at the lower member of the frame; at the upper end oftern must-repeatedly follow each other vertically. the jointline does not, extend accurately in vertical direction, but is inclined tothe one or the other side, as the case may be. Such'faults of stretching will be overcome by the lateral adjustability of the bar 9.

The `bar 9 is provided with a slide 13 carrying a vhand or `index 14 which may be moved towards the vfabric in order to determine the joint between two consecutive portionsy of the embroidery.

The bar 9 is also provided with two colf lars 15I and 16. whichform abutments for the slide13, and,'thus, for the hand 14, too; the collars fix the'end positions of the slide with the hand, the end positions being those given byy thebreadth 'and the position of height of the fabric` joint line need not be equal to the breadth of the embroidery;.it is, in fact, suiiioient to select twoy distinct points of the pattern to determine the joint line with-the aid thereof.

The novel deviceis used as follows If a.y length y.of fabric is to be provided with'a continuous pattern, the one end theref of isv secured to the roller 5 and the fabric portion situated between the rollers 4 and 5 is stretched out between the rails 6 and 7. The thus prepared Vlength of fabric is embroidered in the desired manner. This having been done, and before the fabric portions are exchanged, thebar 9 is so adjusted at thefmovable frame that the hand 14 is in the osition to move along the right-hand bordlering line of the embroidery made, whereafter the bar 9-is fixed in that position by the bolt 12 andits nut. Then the collars 15 and 16 are so adjusted along-the bar 9 that the hand 14 points to two distinct points of the embroidery; thatvis to say, to the onepoint in its one end position and to the other point in its other end position.

To exchange a portion of the fabric for another portion the fabric is detached from y the rails' and 7 so as to become loose, without ythe aid of an additionaly frame, as requisite hitherto, and the embroidered portioniis then wounduponthe roller 5, it being replaced by a blank portion coming ,fromthev roller 4. The, latter portion/.of

fabric is then stretched out between the rails 6 and 7 as formerly, and care is taken that The length of the.

the directive `points of the embroidery coincide with the point lof the hand in its upper position and in its lower one as determined by the collars 15 and 16, the joint line corresponding then accurately to the path of the hand point when the slide 13 is displaced along the bar 9.

The righthand; rim; line of the new portion of embroidery, now. commenced, will then `coincide accurately with the lefthand rim llne of the embroidery portion finished previously, as regards length, direction, and heightadjustment, and it will afterwards;

be impossible to' discover thek connections between. the several consecutive portionsoii theV embroidery which now forms a con,- tinuous whole in Awhich no fault indicating a joint can be detected.

If the same pattern occurs several times above, or below, eachfotherpi. e., in parallel.

stripes in which the -patterned port-ions are located in equal ydistances from one another.,-.

mit lof ascertaining-or examining the jointsl line, but also the distance bet-wee11-the'severaldirect-ive pointsl of the parallel .em-1 broideries located above, orbelowpone an;-: other upon the fabric. That VisA thel more valuableas'the fabric while being kprovided v with the embroidery: is subjected tov distor.`

tions of various kinds whereby faults in. the

joint. line are caused; One ofthe twohands 14 and 14" will, of course, be so arranged at` the slide that the distance betweenl them l can beV altered. v Y

Instead ofA providingk the bar 9 `withA a slide with one or two ormorezhands, such as 14 and 14', the barr 91may .befurnished with a fiat bar 13, carrying a plurality of hands 14 (Figure 3) whichmay be Astations ary or adjustable and each of. which cora; responds toa certain distinct point or marie ofk the pattern, that isto say, of the emry broidery, whereby the distances between they respective points, as well as the directionl of the joint "line, -isv established. It. is, in

this case, not even necessary to make the directive points lie all onv a common line,v` but oneor the other orseveral hands may.V 120 project beyond thevconnecting line ofthe points of the other'hands andmay be ad:

justed with respect to any desiredypoints, lying inthe Vrange of:l the `respective l.proj eetsing hands.l
